LUBRICATOR.

Specication of Letters Patent.

Application sied January 1o, 1913. serial No. 741,188.

T0 all whom t may concern Be it known that I, BENJAMIN F. HOW- ARD, a citizen of the` United States, residing at Indianapolis, in the county of Marion and State of Indiana,` have invented certain new and useful Improvements in Lubricators, of which the following is a specication.

The object of this invention is to provide an eflicient and inexpensive device for lubricating the cylinders and pistons of steam pumps and other minor power generators, and to that end the object is to nebulize the lubricant oil and thoroughly mix it with steam, and then discharge the mixture into the pipe which supplies steam to the cylinder of the motor.

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawing, wherein the invention is illustrated in elevation and partial vertical section.

Referring to the drawing, 1 is the main steam supply pipe through which live steam is conveyed in the direction of the arrows, to the 4cylinder o-f a steam motor (not shown).

2 is an oil vcontainer into the upper end of which the pipe 3, from a steam condenser 4, is introduced and extends to near the bottom of the oil container 2. The condens-er 4 is connected by a branch pipe 5 with the main steam supply pipe 1, and the pipe 5 has a vvalve by. which the discharge through it is regulated. c`The container 2 has a glass gage 7, on o-ne side through which the height of oil in the container is shown, and on the diametrically opposite side of the container is a stand pipe 8 communicating at its lower end with the container 2, near the bottom of the latter.` The stand pipe 8 discharges at its upper end, which is near the top of the container 2, into a horizontal pipe 9. The stand pipe will preferably comprise a glass section through which the globules of oil rising therein may be discerned. The pipe 8 is filled with water, glycerin or the like, in which the oil globules are floated to the level of the pipe 9 through vwhich they are discharged. Between the pipe 3, and the discharge to the stand pipe 8 is a division wall 10 in the oil container making a closure at the bottom of the ylatter but open at its upper end for the passage of the lubricant over it.

All of the parts thus far described are of the usual and well known construction.

The lubricant delivered by the above described mechanism 'into the horizontal pipe 9, has heretofore usually discharged directly into the steam pipe 1 without nebulization or further mixture with steam, and it is between the stand pipe 8 and pipe 1, in the pipe .9 that my invention is employed to nebulize and thoroughly mix the oil vapors with steam before discharge into the pipe 1. To this end I provide a mixing chamber 12, into which the pipe 9 discharges through a downwardly sloping reduced nozzle o-r spout 13, and in front of the discharge end of the nozzle 13, I provide a, nozzle 14 which discharges a jet of steam under pressure in a downward vertical direction across the end of nozzle 13, and forms an atomizer in connection with the nozzle 13, which, when the two nozzles are properly adjusted in keeping with the steam pressure through nozzle 14, thoroughly nebulizes the oil as it is delivered through the nozzle 13, and discharges it forcibly against the oblique lower wall of the mixing chamber 12. The lower end of the mixing chamber 12 i's the discharge end of the latter, and it is provided with a series of oppositely disposed interlapping baie plates 15 and 16 which aid to additionally break up the oil globules and mix the .reduced particles with the steam- The last bathe plate will preferably be sloped in a direction to discharge the mixture in the general direction of the steam How in the pipe 1. Y

Steam is supplied under pressure to the nozzle 14, from the pipe 5,v through the pipe 18, and the pipe 18 will preferably be provided with a valve 19 for regulating the discharge through it. The nozzle 14 is threaded throughout its upper outer portion and screws into a sleeve 20, which is the continuation of the pipe 18 but is jointed vat 21 with the latter to permit separation, and vaccess to the nozzle in sleeve 20. Theupper" inner end of the nozzle 14' has its walls flattened to engage a wrench which is inserted by disconnecting the pipes 18 and 20 at joint 21 to permit of such access, and by meansof the wrench the nozzle 14 may be screwed up or down in the sleeve 20 to adjust the distance of the end of nozzle 14 from the end of the spout or nozzle 13.

v lt will be observed that my invention is constructed in such a mannerl that it is readily `applicable to use with lubricators now inlcommonuse, to render the latter 5 more economical in the use of lubricants,

and more eiiicient.

l/Vhile I `have described my invention with more` or less minuteness as regards detailsv of construction and arrangement and as being embodied in certain precise forms I do not desire to be limited thereto unduly er 'any more than is pointed out in the claims. On the contrary, I contemplate all proper changes in form, construction and arrangement, the omission of immaterial elements and the substitution of equivalents' as circumstances may suggest or necessity render expedient.

I claim: I 1. The combination with a main steam pipe, of a mixing chamber discharging in a downwardly oblique'direction into said pipe, a nozzle discharging oil into said chamber, a second nozzle discharging steam under tenaces pressure across the discharge end of the oil discharging nozzle vand against an oblique wall of said chamber, and balile plates in the chamber between its discharge end and the said nozzles. v

2. rll`he combination with a main steam pipe, cfa mixing chamber discharging in a downwardly oblique direction into said pipe, nozzle discharging oil into said chamber, a second nozzle discharging steam under pressure across the discharge end of the oil discharging nozzle and against an oblique wall of saidchamber, baffle plates in the chamber between its discharge end and said nozzles, and. means for adjusting the relative positions of the two nozzles.

,In witness whereof, I, have hereunto set my hand and seal at Indianapolis, indiana, this, 21st day of December, A. D. one thousand nine hundred and twelve.
